“A set of computer science activities merged to the process of creating, designing and supporting software is called software development.”
Software is the set of instructions that tell a computer what to do. It is independent of hardware and it makes computers programmable.
System software to provide operating systems, hardware management and operational necessities.
Programming software to provide programmers tools like text editors, compilers, linkers, debuggers to create code.
Application software to help users to perform tasks. Media players , Data management software and security programs are application software. Applications refer to web and mobile applications like those used to shop on Amazon.com, Face book or upload pictures to Instagram.
Embedded systems is control devices not considered computers and industrial robots . These devices, and their software connected as part of the Internet Of Things.
Software development is conducted by software engineers and software developers. They are interact and the dynamics vary across development departments.
Programmers write source code for specific tasks like merging databases, routing communications, processing online orders, displaying texts. Coders get instructions from software engineers and use programming languages.
Software developers apply engineering principles to make software to solve issues. They use programming language and tools to make solutions. Software solutions work in the real life like bridges and elevators. They has grown as products increasingly with microprocessors, software and sensors. Software for differentiation, software development must be with the mechanical and electrical development.
Software developers can be involved with notable project including writing program. And they drive the software development life cycle with functional teams to change requirements into features, managing development teams and conducting software testing and maintenance.
The work of software development is not confined to programmers or development teams. Scientists and Engineers also create software code even they are not a software developers.”
Steps in the software development process:
- Selecting a methodology to establish a framework in which software development are applied. It describes work process and roadmap for the project.
- Gathering requirements to understand what is required by users and stakeholders.
- Building an architecture as the structure within which the software will operate.
- Developing a design around solutions to the problems by requirements, often involving process storyboards.
- Building a model that uses a programming language to conduct validation and prototyping of the design.
- Constructing code in the specific programming language. It involves team review to eliminate issues early and produce quality software faster.
- Testing with pre-planned as part of software design and doing performance testing to load testing on the application.
- Managing configuration to understand the software facts and versions of the software. Establish quality assurance and criteria to address and track defects.
- Deploying the software for used to and resolving user problems.
- Migrating data to the updated software from existing applications or data sources.
- Measuring the project to maintain quality of the application lifecycle, and to evaluate the development process with models.
